Tsanangudzo pfupi yekushandiswa kwema sensors mumotokari dzinozvimiririra

Munguva pfupi yapfuura, mota dzinozvityaira inyaya inopisa, uye mishumo ine hukama haina kujairika.Mamwe makambani akaita seBMW, Benz akatotangisa mota dzawo dzekutanga dzakazvimirira.Kune akasiyana marudzi uye mashandisiro emota, kune chaiwo masensa akadaiKIA Auto SPEED sensor, VW Oxygen Sensor uye Toyota Air Flow Sensor.Kuzvityaira hakuchisiri fungidziro kwatiri.

Kuti mota dzizive kutyaira dzakazvimirira, chinhu chekutanga kugadzirisa idambudziko rekuvandudza chengetedzo.Icho chikamu chikuru chinoda kuiswa mari mukati mukati mekuita kweR&D.Mota inoda kuve yakashongedzerwa ne "meso" ane chiono chakanaka uye inopenya "uropi" kuvimbisa kuchengeteka uye otomatiki.Uye "meso" ndiwo marudzi ese ema sensors uye induction faucet yekuyeresa michina.

Mhando ye sensors mumotokari dzinozvimiririra

Iwo ma sensors anonyanya kuve Kamera, Lidar, Radar, IMU uye Ultrasonic radar mune inozvimiririra sensors.Tevere, ngatiunzei ma sensors aya zvichiteerana.

Kamera

Kamera ndeimwe yeayayakanyanya intuitive uye inonyanya kufarirwa ma sensor marudzi, haingoshandiswe mumotokari dzinozvimiririra.Kuzivikanwa kwekamera uye kushandiswa kwevamwe kunoita kuti vaongorori vape akawanda ekubatsira matekinoroji.Nekudaro, kune kubatsira matekinoroji akakwenenzverwa mune mamweminda uye maitiro emisika.Dzese mota dzinozvimiririra uye dzisiri dzakazvimirira dzinoshandisa akawanda makamera, anosanganisira kumberi, kumashure, kudivi uye kwakakura.Nekudaro, tekinoroji yekamera yakashandiswa zvakanaka muindasitiri yemotokari.Iko kusimba kwekamera iyo inochengetwa neyakasarudzika kamera mafudzi bag are low costuye tekinoroji iyi yakakura, nekuti kune vanhu vazhinji vanogadzira algorithms nemakamera.Hutera ndehwekuti kamera inoganhurwa nechiedza chepakati kusvika pamwero mukuru uye zvakaoma kwazvo kuwana chaiyo-dimensional ruzivo (Monocular makamera haagoneke, uye mabinocular kana matatu-ocular makamera akakurudzirwawo).

Kubata

Kuenzaniswa nekamera, Lidar inonyanya kukosha kune mota dzinozvimiririra.Laser radar inozivikanwawo seOptical radar, ichangobva kunzi Lidar.Iyo laser radar ndeyekuzadzisa kuoneswa kwechinangwa nekuburitsa laser beam, kunyatsoonekwa kwayo kwakakwira, iyo yekuona huwandu hwakakura.Nekudaro, izvo zvisingabatsiri zve lidar zviri pachena zvakare.Lidar inonyanya kukanganiswa nekukanganiswa kwekunaya kwemvura uye chando chechando mumhepo, uye mutengo wayo mukuru ndicho chikonzero chikuru chinorambidza kushandiswa kwayo.

Pachangu, chikonzero chakanyanya kukosha nei lidar ichionekwa seimwe yeanonyanya kukosha masensa emotokari dzinozvimiririra mukana wayo mukuvaka matatu-dimensional nharaunda modhi.Laser radar inotumira akawanda-akarukwa laser matanda kuti atore ruzivo rwezvakatipoteredza munzvimbo dzakasiyana, uye kuburikidza nemudziyo wayo wemukati unotenderera, ruzivo rwunounganidzwa mumhando ye360 madhigirii munzira yakachinjika.Chishandiso chinogashira chiratidzo palidar chinogona kunhonga matanda emalaser anoratidzwa kubva pane chinangwa uye oashandura kuita makore.Nekugadzirisa point Cloud data, inogona kupedzisa kugadzika uye kuzivikanwa kweruzivo rwenzvimbo yakatenderedza.Zvisinei, zvinhu zvose zvine zvazvakanakira nezvazvakaipira.Iyo yakawanda-yakawanda-yakarukwa lidar inogona kuona yakakura chiyero chenharaunda, iyo yakakura huwandu hweiyo point Cloud data yainogashira, uye nepamusoro izvo zvinodiwa zvehardware inokodzera kugadzirisa data kugona.Uye zvakare, semudziyo unotenderera mukati me lidar inoda kugara ichitenderera uye kuburitsa laser matanda, iyo Hardware ine yakakwira mhando salmosan azamethiphos zvinodiwa zvekupfeka kuramba uye kurongeka, izvo zvinotungamira kune yakakwira mutengo we lidar uye nekudaro inowedzera mutengo wemotokari dzinozvimiririra. .Nekudaro, sezvo tekinoroji ichikura, zvinotendwa kuti mutengo uye saizi ye lidar ichaderedzwa zvakanyanya, nepo kuita kuchavandudzwa zvakanyanya.

Ultrasonic radar

Ultrasonic radar iri pasi-inofungidzira sensor.Kune maviri akajairika marudzi e ultrasonic radar.Yekutanga yakaiswa pamberi uye kumashure bumper yemota, iyo inoshandiswa kuyera kumashure uye kumashure zvipingamupinyi zvemota.Radar iyi inonzi UPA muindasitiri.Rudzi rwechipiri, rwunozivikanwa muindasitiri seAPA, iultrasonic radar inoiswa padivi pemota kuyera chinhambwe chezvipingamupinyi padivi.Ese ari maviri ekuona huwandu uye nzvimbo yeUPA neAPA zvakasiyana.Nzvimbo yekuona yeUPA inowanzo kuve pakati pe15-250cm, inonyanya kushandiswa kune zvipingamupinyi zviri kumberi nekumashure kwemota, iyo yeAPA inenge 30-500cm.Detection range ye APA yakakura, uye mutengo wakakwira.

Chikonzero chakaita kuti nditaure kuti ultrasonic radar is an under-estimated sensor ndeyekuti inogona kuita zvimwe zvinhu zvakawanda kunze kwekuona zvipingamupinyi zvakaita sekuona nzvimbo dzekupaka uye kumhanyisa lateral kubatsira.

Kukosha kwema sensors mumotokari dzinozvimiririra

Nekukwidziridza kwekuvandudza matekinoroji ekucheka-kumucheto akadai sekutyaira anozvimiririra, kukosha uye chiyero chekupinda kwemasensa zvakagara zvichivandudzwa.Huzhinji hwemotokari dzinozvityaira dzinoda kuvimba nekushandiswa kwemhando dzakasiyana dzemasensa ekuzivikanwa kwakasiyana-siyana kwemifananidzo, inova ndiyo nheyo huru yekuve nechokwadi chekushanda uye kuchengetedzeka kwemotokari.Naizvozvo, mukusimudzira kwazvino kukurumidza kwemunda wekutyaira wakazvimirira, kukosha kwema sensors kwave kuwedzera kukurumbira.Hapana mubvunzo kuti kutyaira kwakazvimirira kuchava imwe yemaindasitiri ekutanga mune ramangwana, uye saizi yayo yemusika inogona kufungidzirwa.Kubva pakuona uku, mukana wemusika wemangwana we sensors uchave wakakura kwazvo.

Summary

Isu tinoziva mashandisirwo uye kukosha kweakasiyana masensa emota inozvimiririra.YASEN mutengesi akanakisa kupa masensa.Iyo inopa marudzi ese ema sensors emhando dzakasiyana dzemota seKIA Auto SPEED sensor.Chero kufarira, unogona kubata nayo.
